PAPER BARRELrf' SPECIFICATION forming part of Letters Patent No. 789,061, dated May 2, 1905.

Application led July 11I 1904. Serial No. 216.040.

To @ZZ whom t may concern:

Be it known that I, HARRISON G. Postr, a citizen of the United States, residing at Manorville, in the county of Armstrong, State of Pennsylvania, have invented certain new and useful Improvements in Paper Barrels, of which the following is a specification, reference being had therein to the accompanying drawings, in which-- Figure l is a perspective view of the completed barrel; Fig. 2,'a' horizontal sectional view thereof; Fig. 3, a vertical sectional view; Fig'. 4, a detail horizontal sectional view of a portion of the barrel; Fig. 5, a detail plan view of one of the barrel-heads; Fig. 6, a detail view of a portion of the blank from which the barrel-body is made, and Fig. 7 a similar view of one of the blanks of the barrel-heads.

One of the many objects of this invention is to provide a paper barrel the body of which is formed of a single strip or band of paper of the proper strength and thickness rolled, by means of suitable shaping-rolls, in spiral form until the proper thickness of material is obtained to give the barrel the desired strength.

Another object of the invention is to so cut and slit the blank that the barrel may be rolled into a regular or standard barrel form having the usual bilge part and to provide means for strengthening the barrel near its ends by inserting between the layers of paper a reinforcing band or bands and forming, by means of said bands, inward-extending shoulders against which the heads of the barrel rest.

Other important objects and advantages of the invention will appear hereinafter.

Referring to the various parts by numerals, l designates the blank of paper from which the barrel is formed. This blank is formed of strawboard vor other suitable paper of the proper thickness and strength and of a width equal to the height of the barrel it is intended to form. This blank is cut out at its edges, as at 2, to form the slightly-tapered parts 2, which correspond in shape to the ends of the ordinary barrel-staves. It is also slit transversely with two series of cuts 2. These cuts are located at the center of the stave parts 2 and terminate a'suitable distance from the longitudinal edges of the blank and short of each other at the middle thereof, so as to leave an uncut portion at the middle of the blank. This blank is rolled, by means of suitablevshaping-rollers, into the standard bilged barrel form, the slits and edge cuts permitting the middle part of the blank to conform to the larger diameter of the middle of the shapingrollers to form the bilge of the barrel, the edges of the stave parts abutting closely together. The blank is wound in volute form until the proper thickness is obtained in the barrel-wall. The various thicknesses of the blank are cemented together during the operation of rolling, and the two ends are securely cemented in place. It will be readily understood that as the various thicknesses are wound around the barrel form the exterior of the barrel-body becomes larger and larger, and consequently the slitsZ and the edge cuts 2 will break joints in the various layers, as shown clearly in Fig. 4, the slits and cuts being formed in the blank equal distances apart. It will be observed also that the two series of slits 2b, Which extend into the stave-like parts 2a, increase the flexibility of the strip of paper-board, and thereby prevent bulging or buckling of the strip when it is wound into layers. This increased flexibility is especially desirable in making a barrel of a continuous strip Where the layers are wound or superposed upon each other, as in this construction the layers must necessarily lie closely together. Any weakness that might result from the slitting is fully compensated for by the strength given to the composite wall by the interposed adhesive, which of course fills into the slits wherever they gap.

The heads of the barrel are formed of paper cut into blanks of the proper shape, as shown in Fig. 7, said blanks being formed by suitable dies to form the main part 3 and the vertical annular flange 4. The blanks are so arranged in the heads that the cut-out portions 5 break joints in the various layers, as shown in Fig. 5, the various layers beingsecurelv cemented together under pressure. One of these heads may be cemented. in one end of the barrel-body, the outer edge of 'the flange 4 being brought Hush with the end of the barrel, as shown clearly in Fig. 3. By forming the heads with a continuous annular ange 4C the chimes of the barrel will be strengthened thereby when the heads are fixed in position.

During the operation of rolling the blanks to form the body of the barrel rings 6 are inserted between the layers thereof near the ends of the barrel to form inward-extending annular shoulders 7. These wires are inserted, preferably, between the second and third layers, into which they are sunk, so that the shoulders will be two layers thick. It will be observed that the notches 2 permit the wire rings or hoops to be slipped or forced on over the ends of the barrel-body after the same is partly formed and that these wire rings serve the further function of end hoops, and thereby assist in rendering exterior hoops unnecessary. It is of course to be understood that they may be inserted at any desired point and that the shoulders may be formed of as many thicknesses of paper as may be desired. It will be noted that by forming the shoulders on the interior of the barrel by means of these wires the exterior of the barrel will be smooth, as shown clearly in Fig. l. The interior shoulders 7 form abutments against which the inner ends of the heads of the barrel abut or rest. These heads may be secured in position by any suitable means, preferably by cement. From the foregoing it will-be readily seen that I provide a strong and cheap barrel,which may be rapidly manufactured and which will be air-tight and waterproof and can be used with or without hoops.

Having thus described my invention, what I claim is- 1. A paper-board bilge barrel-body formed from a single strip of paper-board wound in layers in a volute form, said strip of paperboard being provided with a series of notches f along its opposite edges, forming stave-like parts 2, and two series of slits 2b on opposite sides of the longitudinal center of the strip and extending into said stave-like parts 2, the several superposed layers being cemented together and the notches and slits of each layer breaking joints with the notches and slits of the adjoining layers, substantially as set forth.

2. A paper-board barrel-body constructed of a continuous strip of paper-board wound into layers convolutely and cemented together to form a solid wall, and an interior metal ring inclosed within the layers at each end of the barrel-body and sunk into the inner layers to form an interior head abutment or shoulder and to serve also as end hoops for the barrelbody, substantially as set forth.

3. A barrel-body formed of a continuous strip of paper-board wound convolutely into layers, the superposed layers being pasted together to form a solid wall and said strip being provided with notches at its opposite edges, and interior metal rings inclosed within said layers during the process of winding, the notches in the opposite edges of the strip permitting this insertion to be made.

In testimony whereof I hereunto aliix my signature, in the presence of two witnesses, this 29th day of June, 1904. i
